Consumer projects can receive unreviewed agent instructions that encourage secret exposure and suppress review of the resulting files. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.5.202 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes consumer-project package-manager policy and installs agent instructions and skills. It also creates a review-suppression instruction and carries guidance to expose secrets in documentation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-10T02:35:53.480Z - **Finished:** 2026-09-10T02:37:04.617Z - **Download time:** 511 ms - **Static scan time:** 237 ms - **AI review time:** 70388 ms - **Total time:** 71137 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically changes consumer-project package-manager policy and installs agent instructions and skills. It also creates a review-suppression instruction and carries guidance to expose secrets in documentation. - **Trigger:** npm postinstall during dependency installation - **Impact:** Consumer projects can receive unreviewed agent instructions that encourage secret exposure and suppress review of the resulting files. - **Evidence paths:** package.json, postinstall.js, merge.js, rules/global.md - **Review source:** ai\_review - **Reviewed:** 2026-09-10T02:37:04.617Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic mutation of consumer AI-agent and package-manager configuration - **Attack narrative:** The package's postinstall hook runs without a user command, weakens pnpm lifecycle safeguards in the consumer project, and invokes a merger. That merger writes Copilot instructions, Claude skills, and a rule telling code review to skip its generated files. The installed rules direct users to place real secrets in documentation and explicitly instruct reviewers not to flag this. This is an unconsented, broad AI-agent control-surface mutation combined with reviewer manipulation. - **Rationale:** The automatic install hook modifies consumer configuration and agent control surfaces, then installs review-evasion and secret-exposure guidance. The absence of observed network exfiltration does not neutralize this concrete lifecycle abuse. - **Files touched:** .npmrc, .github/copilot-instructions.md, .github/instructions/\*.instructions.md, .github/instructions/no-review-docs.instructions.md, .claude/skills/\*, AGENTS.private.md, .github/PULL\_REQUEST\_TEMPLATE.md ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The npm postinstall hook automatically edits the consumer project's .npmrc to force dependency lifecycle scripts and disable pnpm's side-effects cache., Postinstall then launches the merger in the consumer project, which writes Copilot instructions and copies Claude skills into agent control surfaces., The generated Copilot instruction tells code review to skip the package's generated rules and templates., Package rules instruct authors to embed real tokens and keys and tell reviewers not to report that as a security issue. - **Evidence against:** No outbound network or credential-exfiltration code was found in the inspected JavaScript lifecycle path., No runtime dependency on another release of this package was declared. ## Affected versions and remediation This report applies to @routerhub/agent-rules@1.5.202. - Avoid installing @routerhub/agent-rules@1.5.202. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
